the mouth, which is surrounded by a bead or lip 4, the latter together with an annular ledge or seat 5 comprising the usual annular recess 5, which receives and supports the cap or closure, as 6, by which the mouth is sealed. The closure 6 is preferably composite, and consists of a plane disc 6, which rests upon the ledge 5, its diameter preferably being such that force is required to effect the firm seating of the disc, and at the same time dispose its periphery in sealing contact with the vertical shoulder or wall 4 of the recess. Upon the disc 6 is mounted a circular cover 6 consisting preferably of relatively thin flexible fiber, such for example, as'pulp-board, and the like, the said cover comprising a plane disc-shaped medial portion 6*, of substantially the same diameter as the disc 6, which overlays the said disc, and may be permanently secured there to, by light wire staples 7. clinching of the and rigidly part. The central portion 6" together, as one by an annular flange of the cover is skirted 6, the latter preferably being rolled or vmolded convex to conform to the flare of the mouth 3, the said flange being of such breadth as to overlay and shield the entire top as well as the inner face of the bead from dirtand germs. during ,the interval between the filling and the dispensing of the contents of the bottle. Ordinarily, the disc alone will produce a satisfactory sealing of the bottle mouth, but in order to do this effectively, the said disc must be relatively thick and inflexible, in orderto withstand rough handling, without being loosened or displaced sufficiently to allow the contents of the bottleto escape, or germs to enter the neck 2. The cover 6*, it will be understood, may be applied to the bottle mouth alone, for effectively shielding the lip 4, provided fiber of suitable thickness and pliability is employed, for enabling the cover to be properly seated in the recess of the mouth, and rendered self-supporting. In either case, the extra weight of the material and the extra time and means required to produce and apply the said parts separately, greatly increases the cost of manufacture and tends to curtail production and limit the use of the detached parts. The present invention has for its particular object to provide a combined closure and sanitary protector for The proper staples tends to draw and tainer escaping,

bottle mouths, all parts of which ,may be made of relatively light-Weight fiber, which when fabricated into one part, is consider ably lighter than the combined weight bf the detached members. This materially quickens and cheapens the production besides reducing the capping workv to a single operation. Furthermore when the parts are rigidly bound together, as shown, the relatively light primary sealing member 6 becomes reinforced to such extent that the central portion of the closure is really thicker and stiffer, and therefore produces a more substantial of the closures heretofore used. Furthermore, by combining the relatively lightweight disc and cover, in themanner shown, not only greatly facilitates the packing, applying and removing of the closure, but each of said parts tends to reinforce and supplement the other, for producing a highly efficient and sanitary closure, which will withstand rough handling, and may be exposed to dust, dirt and other deleterious elements, without danger of the contents of the conor the pouring-mouth of the bottle being rendered unsanitary. The closure 6 may be readily and quickly removed for dispensing the milk, or other contents, by prying upwardly the convex flange 6, elther with a knife or by the use of the fingers.

In Figs. 3, 4 and 5, the order or arrangement of the disc 8 and the cover 8', is reversed. That is to say,- the disc 8 is mounted upon the depressed plane portion 8 of the cover, to which it may be permanently secured, by any suitable adhesive, as indicated at 9 (see Figs. 3, l and'5). In this modified closure the primary sealing of the contents 'of the bottle 2, is ,efi ected by the direct contact'of the portion 8 with the ledge 5, supplemented by similar contact of the periphery of said portion, with the shoulder of and effective sealing, than many member and the recess, the depth of the seal at this point being increased, and the sealing being rendered more eflective by the thickness of the disc 8, the latter preferably being of such diameter as to efiect a close and tlghtjoint with the base of the flange 8 of the cover, when the closure is applied by the capping machine. By adhesively uniting the parts 8 and 8, as shown and described, these members may be handled as one part, and fiber of relatively light gage may also be employed for producing the said members.

The disc 8 and the cover 8 may follow the v substantially same construction, and perform the same functions, as the corresponding parts of Figs. 1 and 2.

Having thus described my invention, what I claim, is-

A bottle closure comprising a thin and freely flexible member of uniform diameter throughout having a central substantially flat portion and a curved annular "portion formed to overlie the bead of a bottle mouth, a disk underlying the central portion of the being formed to seat on the ledge of the bottle mouth, said disk being stiff and of greater thickness than that of the body and means to secure the disk to the central portion of the member with the entire area of the disk in intimate contact therewith and atpoints throughout and adjacent to the periphery of the disk consisting of a series of staples arranged in circular formation and disposed spaced from the center of the disk and adjacent the periphery thereof whereby upon lifting of the curved annular portion of the member, the disk will be lifted from the ledge by power applied at a point adjacent to the disk periphery thereby to prevent tearing or distortion of the disk.
